ANSWER:
Andean apex is the kind of mountain formed due to an oceanic plate and continental plate colliding.
Step-by-step explanation:
- The process of the collision works when the oceanic and continental plate collide.
- Due to the process, oceanic plate is pressed under the "continental plate" which is caused by higher density of oceanic plate.
- The process continues, later magma rises up from the subduction zone which causes high compression to the mountain belt and mountain ranges.
